Application filed August 28, 1912. Serial No. 717,451.

extremely simple in its construction and one that may be readily used in connection with existing time devices for producing the desired results.

Une form of device embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which- E'igure l is a view in side elevation oi a gas fixture showing my improved device forming part thereof. Fig. 2 is view in section thereof on plane denoed by dotted line 2-2 of Fig. 1. Fig. 3 is a detail view in horizontal section through the device on plane denoted by dotted line 33 of Fig. 1,

a number of stops, one at least of which is to.

limit the movement of the valve when it reaches an extreme position (either open or closed.) and two at least of which shall limit the movement of the valve when it reaches the opposite extreme position. For example one stop may be employed to limit the movement of the valve when it reaches its closed position and two to limit its movement when it reaches its open position, or one stop may be employedto limit'the movement of the valve when it reaches its open position and two to limit its movement when it reaches its closed position. The term extreme position is employed to describe the valyewhen it is either opened-enclosed, thatais,

' notches l2 and a setof shut-oii note in when the valve is closed it is in one extreme position and when it is open it is in the other extreme position. In the form of device herein shown a number 01 stops for limiting the movement of the valve when it reaches eitherof the above mentioned p,ositions are employed, these being in the form of notches in the lower edge of the valve body and consisting of a set oiiopening each of these sets consisting of ewe no .es located on diametrically opposite sides of the body.

The plug is provided with a thumb piece *13, of any suitable form and construction, and a'latch 14: is pivotally mounted on this thumb piece 13, one end of the latch being formed and located in a position to enter the notches 5 .or 12. A spring 15 may be employed to hold the latch, so that its end will normally engage the sur- "306 of the casing 8 and within the notches 5 or 12, and a holder 16 is constructs l e the opposite end of the latch to M it, when. desired, with its notch end out oi engagement with the outer i face of the casing 8 and so that this en will notengage said stops.-

The end of the thumb piece 13 is suitably formed to receive the key 17 of a time SUCQ 18.v This time piece may be of'any well known form, the key 17 constituting a part of the alarm mechanism of the clock constructed and operating in a manner. well known. A support 19 may be employed as an additional means .ior suspending the clock or time piece 18 in position.

In the operation of the device the alarm mechanism of the clock is wound in the ordi nary manner and set to'operate at the de sired tune. The clock 1s then suspended from the gas fixture, as shown in i,

and the plug 10 is turned to the'position shown in Figs with the latch M- fiust dis engaged from one of the notches 12. The turning of the plug to this extent does not materially affect the flow of gas, which is supposed to be lighted. At the required time the alarm mechanism will he operated and, in its turning movement, will rotate the plug 10 from its open position shown in Fig; 4 to its opposite or closed position to shut oii the gas, the latch i l engagii'ig the next succeeding shut-oiinotch 12 1d stopping the rotation of the parts when the plug is in position to shut off the If it be desired to turn on the gas at a certain time the same operation is followed with the exception that the plug 10 is located a quarter of a turn from the position shown in the drawings and with the latch disengaged, but resting close to the edge of a shut-off notch as hereinbefore explained. A pilot light 20, formed by a tube extending from the gas pipe, islocated in proper position with respect to the burner to ignite the gas when it shall be turned on, it,.of course, being understood that the pilot light is in operation in the usual manner. The alarm mechanism now being operated at the desired time the plug 10 is given a quarter turn from its closed position to its opposite or open position, and the latch 1 L engaging with the next succeeding opening notch stops the operation of the parts with the gas turned on, and the burner,therefore, lighted. The term position as employed in the claims herein is'intended to designate the condition of the valve and as qualified by the terms open and closed. It will be seen that a gas cock is provided in which the,plug may be moved from either of its extreme (open or closed) positions to its oppdsite (either closed or open) position, by a power driven device rotating the plug always in the same direction. That is, if the plug is in one extreme or open position, the power driven device may be employed to move it in a certaindirection and the stop will operate to stop movement when the plug reaches its opposite extreme or closed position, and likewise if the plug is in one extreme or, closed position the power driven device may be employed to move it in the same direction as before and the stop will operate to stop movement of the plug when it reaches its other extreme or opposite or open position.

If it shall be desired to operate the device for the purpose of attracting attention, as in the case of illuminated signs or the like, the latch 14 may be engaged with the holder 16, and then, by attachment of a proper device to the thumb piece 13 to rotate it at such speed as may be desired, the gas will be lighted, and then immediately extinguished and then again relighted and so on.

While I have illustrated my invention as applicable to a lighting fixture employing gas as an illuminant, it will be understood that my improvement may be applied to any lighting fixture.

While I have shown and described herein a preferred form of mechanism for accomplishing my purpose, it is not essential that a device shall be constructed precisely as shown herein to contain the invention, and

the latter is, therefore, not limited to a device constructed in exact accordance with L that herein disclosed.
